【 摘 要 】

In order to explore the influencing factors of regional energy consumption and guide energy conservation policy, this paper analyses the difference of energy consumption from the perspective of technology and efficiency. Based on the PDA decomposition framework, the Shephard distance function and the Malmquist index are introduced to decompose energy consumption changes into five parts and build a comprehensive decomposition model of energy consumption. The model considers several factors that affect the changes in energy consumption, and then analyses the changes in China's energy consumption from 2007 to 2013. The results are as follows: Potential energy intensity and potential capital output are the two main factors that affect China's energy consumption; among the factors driving the growth of energy consumption, the impact of potential per capita capital far exceeds the population change; technological progress and technical efficiency show more obvious regional characteristics, among which the former shows positive energy conservation mainly in the eastern region, while the latter shows significant suppression effect on energy consumption in the western region.
